The latest poll from Suffolk University shows Democratic Rep. Ed Markey leading Republican Gabriel Gomez 52%-42% in the special Senate election held tomorrow. That puts it roughly in the midpoint of the June special election polls as aggregated in realclearpolitics.com. So it’s not a very interesting result, given that we’ll know the actual election results in less than 48 hours.

But there is one interesting thing in the poll. Suffolk asks Massachusetts voters to rate Obama’s performance and to say whether they have favorable or unfavorable feelings about Barack Obama. As is often the case, his fav/unfav numbers are somewhat more positive than his job approval. But in both cases his numbers in Suffolk’s Massachusetts special Senate election voters have been plummeting.
